I don't use hibernation on my laptop, but only sleep. It has 16GB RAM, and 16GB swap would remove 33% of its overprovisioning to no purpose. I have a tower with 14GB of RAM and that has ½GB swap which has never been used, except when I borrowed it for /boot when trying out a fully encrypted system. > "free -m" just now shocked me by saying this HP is only using 89mb of > swap.

I would have expected swap usage to drop dramatically when it hibernates because you've got to have room for what's in memory, compressed I grant you. Won't it drop a load of RAM caches that it was holding onto? > Thank you, Developers! I agree that things swapping in and out > painfully clog the system.

Most of my machines have much less RAM than the two mentioned, though they get less memory-intensive use nowadays. Maybe the difference is that I don't install any DEs here. Cheers, David.
